The SB47 stabilizing brace is an awesome invention that secures AK style pistols to the forearm of the shooter and assists in firing the pistol the way it is intended, with one hand. Using the SB47 in this way, recoil is reduced significantly, resulting in more accurate shooting without compromising safety, comfort or control. Designed and made by a U.S. Military veteran with help from a top V.A. prosthetic specialist, the intent and design of the stabilizing brace is to help America's wounded veterans enjoy large frame handgun shooting again. The concept was to invent and create a device that would act as an extension of one's own arm, so it is like a part of your body. Well the SB47 did that - and more! Not only did it help our wounded heroes regain their confidence and handgun skills, it was wicked fun for anyone to use! BATF approved for everybody, the SB47 does not require any special permits, doctors notes or SBR tax stamp!
